问题
Usually a solr query with facetting option returns the results in sorted order based on the facet count. When I set the facet limit to -1 the results were not returned in sorted order; this means I have to do the sorting manually in the server side.
Should I need to append anything more in the solr query to get it in a sorted order?
回答1:
please try facet.sort=count
The default facet order is base on the count, descending order, but it will return the index order rather than count desc order if facet.limit is less than 0
Details can be read from Solr Wiki
